My "family" is multiple devices. M networks (hotel, airport, lounge) and N devices means O(M * N) wifi setups, so carrying a known 200g router means I only have to do O(M+N) setups.

But yeah I also have P family so O(M * P * N) would be a headache.

If your home WiFi uses PSK auth like 99.223% of all homes, you can get to 0 setups by using the same WiFi SSID+PSK on your travel router as the one on your home network.
